Double-sided carbon oil circuit board

Overview of Carbon Ink PCB Carbon ink PCB (printed circuit board) is a PCB where carbon-based conductive ink (referred to as carbon ink) is coated on the PCB substrate and cured to form a PCB with a carbon film conductive pattern. As the market demands for reducing PCB production costs continue to rise, replacing expensive golden keys with carbon oil keys has become a general trend. Carbon oil board is a commonly used surface treatment method for single and double PCBs, ensuring reliable long-term operation through processes like inspection, testing, and burn-in testing. Characteristics and Uses of Carbon Ink PCB Properties of Carbon Ink Carbon ink exhibits strong adhesion, peeling resistance, and wear resistance, withstanding up to ≥1 million cycles and a resistance change rate ≤10%. Compared to other metals, the square resistance of conductive paste is relatively large, but the carbon oil plate’s square resistance can generally be controlled at ≤ 20 ohms, offering hig…
